Turmvilla scenario keyboard input stuck in a subsystem

[Duss Pirmin]

Hello

I'm playing around with the Turmvilla scenario as Norman provides it.

Sometimes the keyboard input will be stuck in one of the started  
subsystems. Mostly this is the case with the linux subsystem (I only  
recognize this when I shut down linux and want to close the nit_fb),  
but I also had the case where it was stuck in the noux subsystem.

Is there a way to unstuck the keyboard, or a way how I could debug  
what happens?

Best Regards Pirmin
